Yep that big old 40 that is barely 3/64" bigger in diameter has more energy than the puny nine, if velocity is equal. More force/energy, more "knock down power", sure. I wonder how many love the big old .40 and have a scale that has the very fine lines of 1/64ths of an inch can actually see how much 3/64ths is without reading glasses or a magnifying glass Does the .40 actually achieve the same velocity with 180 gr bullets as the nine with 124 gr +P ammo. Not quite
